MAX MARC GUGGENHEIM, OF SAGINAW, MICHIGAN, AND GEORG-E RALPH BAKER, OF WILLESDEN, LONDON, ENGLAND, ASSIG-N ORS TO BAKER PERKINS COMPANY, INC., OF SAGINAW, MICHIGAN, A CORPORATION OF NEW YORK CQNFECTIONERY Application filed January 28, 1330, Serial No. 424,120, and in Great Britain January 30, 1929.

This invention relates to a method and means for delivering chocolates from a chocolate coating machine to suitable trays or collecting devices.

1 5, The object is to provide an improved meth- 'odof treating coated chocolates and improved means for :discharging them, wherebydischarge is carried out with the minimum of manipulation, rendering unnecessary the ,ml use of paper sheets for the collection of the goods. f l

The freshly coated chocolates are received upon a traveling surface rendered neutral by a coating or'impregnation of tempered chocolate. Such surface preferably passes through zones Vof decreasing, and if required, increasing temperatures and discharges upon a receiving conveyor element which travels at suitable speed in a direction substantially go in alinement with the direction of movement of the said tempered surface.

According to the present invention, an endless transfer conveyor of linen, silk or other suitablematerial.receives the chocolates as ,25 they arrive from a coating mechanism via edge. The return lap 'of the-conveyor is immersed in a tempering bath of chocolate and Sligo is thereby coated and impregnated with chocolate. A scraper is `provided to adjust the thickness of the layer of chocolate and thereby establish a desired surface quality of the conveyor as it passes for the reception lof the chocolates.

The chocolates are delivered by the transfer trays are cooled after depositing and are then subjected to vibration or knocking tovloosen the goods for removal.

In the accompanying drawings'Fig. l is an elevation partly in section, ofl an apparatus according `to the invention.

Fig. 2 is a corresponding plan. i

Fig. 3 is a transverse section on -lineS-S of Fig. 1.

In carrying the invention into efect according to one convenient mode, an endless conveyor band 3.of silk, linen or `other suitable material is supported upon a convenient guide member or blade 4 .which is located adjacent the usualv wire belt :5 that delivers freshly coated pieces from a chocolate coating mechanism 6.` The blade 4 extends in a plane in continuation of the Wire belt toward a delivery position where the conveyor band 3 passes ,over ablade edge` `7. rIhe return lap 3a of the conveyor is guided over the edge of a chocolate bath 8 (which may be jacketed), by means of a roller 9 yand thence passes through the chocolate by the aid of a roller 10 of comparatively large diam-eter. Roller l0 may also serve to drive the transfer conveyor band.V A

The driving of band 3 may, if desired, be aided bythe roll9, which is spring floaded Vand driven positively in synchronism with the main driving roll 10. f

A plate or chute Il is arranged from the lip of bath 8 towards knife edge 7 'to collect any chocolate which may drip from the conveyor band and to drain it back into the bath. On the `egress run of the band from the chocolate bath a scraper device is provided, comprising a'pair of `blades 12, 13 uponopposite sides of the band. The coat of chocolate adhering to the band may thereby be adjusted to a predetermined appropriate thickness. The Scrapers may leave a thin layer or coat upon one or both sides of the band, or they may deprive the band of a discernible coat of'chocolate, leaving it sufficiently impregnated to present a non-setting surface to the chocolates received from `the coating plant. 2

VPreferably the. conveying lap of the transl During the passage of the chocolates along the transfer conveyor they `may' be treated in zones of different temperatures, forexample, heating means, such asa water jacket may be provided under the table, adapted to keep the chocolates warm in the early stages, as they move along the transfer conveyor, and means may also be rprovided for l gradually lowering their temperature as they proceed further along the transfer conveyor to discharge at the blade edge.

Alternatively, cooling may be effected in the first stage followed by a short period of rather intense heating Vto remelt a thin layer so that the goods will' easily detach lthemselves from the *ba-nd.

The chocolate bath 8 is carried by side cheeks supported upon bolts 16 on a bracket 17 associated with the coating plant 6.

'Vertical adjustment of the side cheeks rela- Vtively to the coating plant is effected by means of nuts 18. y

Driving roller 10 is mounted on a spindle 19 thatv rotates in bearings in side plates 27 within vthe chocolate bath 8. The spindle 19 is provided with a gear wheel 20 with which neshes one of a pair of pinions 21, 22 mounted on a spindle 23. The outer pinion 22 gears withV aspur-wheel 24 that is connected to a y Vchain wheel 25 driven from aA chain wheel 26 iii) associated with the coating plant.

VThe side plates 27 are supported on two concave Ysaddles 27 a attached to the inside of vthe chocolate bath 8.l The transfer conveyor unit moves pivotally about the axis of the spindle 19 when the table is adjusted by means vof screws 39. Screws 28 are threaded in the plates 27 andV workin arcuate slots 29 lin the outer plates 15, holding the plates 27 .down to resist the driving thrust of the gears thezplates'27.v Roller 9 may thereby be adjusted to alter the tension of the band 14. The roller 9 is pressed against they roller 10 by tension of the springs when suitably adjusted by the screws 33. The conveyor band 3, being thin, is propelled without danger of strain or tearing, by being yieldingly clampedbetween the positively driven rollers 10 and 9.V The roller 9 is provided with a pinion34 meshing with and driven by the gear wheel 20.

transfer band. The blade delivering edge 7j The scrapers 12 and 13 are carried by the plates 27, scraper 12 preferably being fixed. Scraper k13 is carried by a pivotally mounted rod 35 that is held in adjusted position by the clamping screw 36.

The blades 4 and 7 are preferably supported by bars 37 which are slidably mounted upon the table 14. Adjusting screws 38 are provided whereby the blades may be adjusted longitudinally onthe table. At its forward end the table Ais provided with adjustable supporting screws 39 carried by a transverse bar 40 to enable it to be supported from a suitable support.

Heaters 41, 42 are provided forthe Abath and chute 8 and 11 respectively, and tempering baths 43, 44 for the table. f

In practice, the chocolates are received from transfer conveyor 3 onto another ifconveyor (not shown)V which passes them into acooling chamber so theymay be conveniently collected when they are in appropriate condition. According to one form,y ancinclined endless conveyor 45 which may be provided with, for example, metallic rigid tray elements 46, is arranged so that the chocolates c are received on the tray elements which are only slightly inclined to the direction of the path of the chocolates as they pass along the of the transfer conveyor 3 causes transfer of the chocolates evenly and without subjecting them to shock or other treatment liable to damage their coating or shape. The thinness of the blade edge causes the chocolate coated-. piece to leave the conveyor band suddenly, yet without shock. The quick separation prevents formation of tails. 'l

Having thus described our invention, what we claim and desire to secureby Letters Pat-5105 ent is: Y

l. Apparatus for discharging chocolates from a coating machine, comprising an end-y less transfer conveyor band, of fibrous material permeable by melted chocolate, adapted?. to receive the chocolates from the coating machine, means for guiding a lap of the transfer conveyor band in immersed reliationship with a tempering bath of chocolate and means engaging the band after emerg-y ing from the bath adapted to gauge the thickness of the chocolate coat on the band prior to the depositing of the goods on the'band. v

2. Apparatus for discharging chocolates from a coating machine,comprising an endless transfer conveyor formed of thin permeable fabric, and adapted to receive the chocolates from the coating machine, such conveyor being impregnated with tempered chocolate prior to the depositing of the pre? viouslychocolate-coated goods on the band, whereby breaking of the bottom coat-ing and tailing are avoided duringl such transfer.
